How do I move on after a break-up?
Why parting hurts so much
Every relationship in this world brings joy in meeting and sorrow in parting, and attachment (aasakti) makes that sorrow burn. Sorrow in parting comes with moh (clinging attachment); in prem (love) it does not.
Say there is love for you, and attachment to you. When you go away, that heart stays in pain. It keeps burning.
